Crowley's barge Progress is being pushed up the Savannah River by an unseen Crowley tug. As more ocean-going ships are powered by liquefied natural gas, it became necessary to develop LNG fueling infrastructure. For the LNG bunker Progress, Crowley partnered with Fincantieri Bay Shipbuilding (of Sturgeon Bay, Wisconsin) to build the 416-foot barge, with a capacity of 3.17 million gallons of fuel.
